High-Efficiency Solar Electricity of Umbrella by TRIZ Analysis

Abstract

This investigation presents the strategy of high-efficiency solar electricity of umbrella by TRIZ (Theory of Inventive Problem Solving) analysis. According to the combined statistics of classical and new contradiction matrix, the invention principles can be used for designing tracking irradiance of surface plane of umbrella orientations including tilted angle (θ) and azimuth angle (Ø). Three geographical sites are discussed by regions of Berlin, Taipei and Wellington located in north, near and south of tropic of cancer, respectively. The optimal design of azimuth surfaces of umbrella can be obtained by electricity gain at a fixed tilted angle.
